Hot do I link MPFR in CMake? - cmake

Question

I'm totally new to cmake, I'm on MacOs and I'm trying to build a c++ library and I need to link my executables to mpfr in order to make it work
This is my CMakeLists.txt file:
cmake_minimum_required(VERSION 3.19)
project(my_project)
set(CMAKE_CXX_STANDARD 14)
add_executable(my_project main.cpp)
find_package(GSL REQUIRED)
target_link_libraries(my_project GSL::gsl GSL::gslcblas)
find_package(Boost REQUIRED)
target_link_libraries(my_project Boost::boost)
find_package(MPFR REQUIRED) # <- It fails here!
target_link_libraries(my_project MPFR::mpfr)
When I try to build my project with CLion I get the following error:
CMake Error at CMakeLists.txt:13 (find_package):
By not providing "FindMPFR.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "MPFR", but
CMake did not find one.
Could not find a package configuration file provided by "MPFR" with any of
the following names:
MPFRConfig.cmake
mpfr-config.cmake
Add the installation prefix of "MPFR" to CMAKE_PREFIX_PATH or set
"MPFR_DIR" to a directory containing one of the above files. If "MPFR"
provides a separate development package or SDK, be sure it has been
installed.
After some research I found out that Cmake was linking correctly both GSL and Boost because there are both a /usr/local/share/cmake/Modules/FindGSL.cmake and a /usr/local/share/cmake/Modules/FindBoost.cmake file, So I looked online for a FindMPFR.cmake file to insert into the /usr/local/share/cmake/Modules/ directory, I tried with this one but the error remains the same. What am I doing wrong?
Edit:
Ok now my CMakeLists.txt file looks like this:
cmake_minimum_required(VERSION 3.19)
project(my_project)
set(CMAKE_CXX_STANDARD 14)
add_executable(my_project main.cpp )
# Append the cmake/ directory to the CMAKE_MODULE_PATH
list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake")
find_package(GSL REQUIRED)
message(STATUS "GSL Found: ${GSL_FOUND}")
target_link_libraries(my_project GSL::gsl GSL::gslcblas)
find_package(Boost REQUIRED)
message(STATUS "Boost Found: ${Boost_FOUND}")
target_link_libraries(my_project Boost::boost)
find_package(MPFR REQUIRED)
message(STATUS "MPFR Found: ${MPFR_FOUND}")
target_link_libraries(my_project ${MPFR_LIBRARIES})
And it works fine :)
